Based on the preliminary test, different concentrations were tested to determine the toxicity of the insecticide to each population.

Our results observed that ABA group showed significant changes pmelatonin. To investigate the molecular weight of protein was done by SDS-Page electrophoresis.

Two endophytic fungi, i. The radiosensitivity of Spodoptera Frugiperda Smith Abbot larvae raised with two different diets natural and artificial was studied using doses between 20 and Gy, in Co gamma source with a dose power of On the contrary, in Salta and Jujuy Ch. The research was conducted at a Balitkabi screenhouse in February haama, using randomized block design and each treatment was replicated three times.

Then, based on these results, the efficacy of the selected doses, Gywas evaluated on the metamorphosis, degree of malformation and reproductive behaviour of S.

Ovicidal Activity of Couroupita guianensis Aubl. In general, Noctuidae species have morphological similarities that have caused some difficulties for assertive species identification by conventional methods. Zn accumulation, metallothionein and cell ultrastructure of the midgut.

The results showed that there was effect of all isolates on egg mortality. The feature selection method employed in this study is the Replacement Method, which has proven to be successful in previous analyzes.

spodoptera litura larvae: Topics by

The activities of digestive enzymes, trypsin and chymotrypsin, were reduced by feeding larvae with 0. Results revealed that hexane, chloroform and ethyl acetate extracts of C. The maximum mortality of first instar larvae was We also conducted the comet assay immediately after irradiation and over the following 5 days period. Eggs were also collected from tree plants but larvae did not complete their development.


Therefore, it is necessary to develop for environmentally friendly insect pest management techniques such as the activity of liquid smoke made from tobacco stem waste as an insecticide to Spodoptera litura. An insight into the molecular mechanisms and components related to Vip intoxication will allow designing of more effective management strategies for pest control.

The other part of research was carried out in Balitkabi Breeding Improvement Laboratory. Digestion of viral DNA with three restriction enzymes showed that the genome pattern of baculovirus isolated from Bantul were close to SpliNPV isolated from Japan and those of Spodoptera littoralis and quite distinct from those isolated from Southeast Asia region.


Azadirachtin was applied topically, via injection or oral administration. Spodoptera eridania, Spodoptera frugiperda, Spodoptera littoralis, and Spodoptera litura Lepidoptera: Each treatment had 5 repetitions with 20 larvae with days of age in the total of larvae per treatment.

Addition of specific inhibitor chaetocin resulted in decreased histone methylation level and host chromatin relaxation. Irradiation effect on the growth index was mainly due to reduction in survival, which was further pronounced spodopter to delay in development. Larval development and survival were analyzed by infesting leaves of maize, grain sorghum, Johnson grass, soybean, Brachiaria and tobacco with FAW newly hatched larvae in a no choice test.

Gel immunodiffusion tests showed no serological relationship between PaV and Nodamura virus, the type species for insect nodaviruses. Despite the importance of its natural enemies, there still is a lack of information about parasitoids species that attack this insect-pest, such as larval parasitoids.

Phenotypic identification of soybean lines against armyworm pest resistance Spodoptera litura F. The life cycle of S. The extract was litur by maceration and evaporation and followed by particles stabilization.

The longevity of the tropical army worm was slightly affected by gamma irradiation. The instances of down-regulation were independent of the signaling pathways mediated by defense-related jasmonates but were relevant to the levels of PAP1-induced and herbivory-suppressed transcription factors, An1a and An1b. Results from choice tests.


The objectives of this study were to characterize and to quantify the potential damage of S. Free-choice and no-choice feeding non-preference tests were done using two newly-hatched larvae per genotype or one third-instar larva per genotype in both tests. However, electron beam irradiation did not induce the instantaneous death of S. Chemical methods have failed to control this pest as this has developed resistance to almost all synthetic insecticides available.

Younger and middle ages have no influence on the mating. The planting media were plastic pots diameter 18 cm filled with earth, two seeds per pot were planted and intensively raised. Mortality Dynamics of Spodoptera frugiperda Lepidoptera: Full genome sequence and phylogenetic analyses showed that this virus was closely related to variants in Heliothis virescens ascovirus-3a, and it was named HvAV-3j.

Interspecific competition between Snellenius manilae and Meteorus pulchricornis, larval parasitoids of Spodoptera litura. The objective of research was to determine the resistance level of Spodoptera exigua populations collected from the district of Sanden, Kretek, Wates, Temon, Panjatan, Wonosari, Panggang and Playen all are in Yogyakarta Province to chlorfluazuron insecticide.

Among these plants, the neem tree, Azadirachta indica, is commonly used against several insects, mainly Lepidoptera.

Full Text Available A Baculovirus has been isolated from cadaver of larvae of Spodoptera lituraa Noctuidae of agricultural pest, importance due to its wide-range hosts and the damage to their respective host. The other part of research was carried out in Balitkabi Breeding Improvement Laboratory. The main interest of developing trustful QSAR models is that these enable the prediction of compounds having no experimentally measured activities for any reason.
